Abstract:The complexity of technological innovation makes the innovative ecological network gradually being the new main form of technological innovation in China's automobile industry. The historical complexity of technological innovation in China's automobile industry makes it more realistic to study its development and evolution process. This paper systematically studies the external form and internal structure of technological innovation network in China's automobile industry, reveals the operating mechanism of four main forms of innovation in China's automobile industry, and shows the evolution process of four types of technological innovation network, i.e. automobile enterprise-oriented, industry chain-oriented, industry-university-research Alliance-oriented and innovation ecosystem-oriented, in order to develop the technological innovation network in China's automobile industry. Network development provides more feasible theoretical support.
